An Opening and Shutting Structure of a Cover for Electric Rice Cooker}

The present invention relates to an electric pressure rice cooker lid, and more specifically, to provide a rotation member to the pressure lid to smoothly open and close the lid can be made as well as a safety pin to open and close the lid safely. It relates to an opening and closing structure of the lid cover electric pressure cooker.

In general, the electric thermal pressure cooker has a structure to open or close the lid formed on the top of the cooker to put the food in the inner pot to cook or to take out the food of the inner pot to the outside. The electric insulation pressure cooker should be firmly coupled to the inner pot and the lid as the inside of the inner pot is very high heat and pressure is generated during cooking. To this end, it is configured to be coupled to each other by forming a plurality of engaging projections and engaging grooves on the inner periphery of the pot and the lid. The opening and closing operation of the lid is made by rotating the lid through the rotation knob, the operation of the plurality of the engaging projection and the engaging groove formed on the inner pot and the lid detachable from each other.

For example, according to the opening and closing structure of the electric pressure insulating rice cooker lid according to the prior art, as shown in Figures 1 and 2, a plurality of locking projections 42, 56 on the periphery of the pressure lid 40 and the inner pot 50 ) And engaging grooves 44 and 54 are formed to correspond to each other, the pressure lid 40 is coupled to the rotating plate (not shown) and the fixing bolt 46 is installed to be rotatable in the outer cover 30, One side circumference of the pressure lid 40 is provided with a handle 60 to enable the pressure lid 40 to rotate.

However, according to the opening and closing structure of the electric pressure insulating rice cooker lid according to the prior art, the rotational force during the opening and closing operation of the pressure lid 40 through the fixing bolt 46 by the rotation operation of the handle 60 installed on one side of the lid. If the handle 60 is not rotated exactly in the horizontal direction as it is transmitted to the rotating plate, the rotating pressure lid 40 is biased to rotate. In this case, the locking protrusions 42 and 56 and the locking grooves 44 and 54 formed in the pressure lid 40 and the inner pot 50 are not accurately engaged, and thus the pressure lid 40 cannot be closed. Due to the severe frictional force in the eccentric portion at the time of opening 40) there was a problem that the pressure lid 40 has to be rotated to give a lot of force.

Then, as described above, if the lid is forcibly rotated when the pressure lid 40 is opened, a gap is generated in a portion of the fixing bolt 46 that couples the rotating plate and the pressure lid 40, and the pressure inside the inner pot. There was a problem to shorten the endurance life of the pressure cooker.

In addition, the handle 60 is protruded to the outside to give aesthetically unpleasant, there was a problem that takes up a lot of use space during storage.

Accordingly, the present invention has been made in order to solve the above problems, the purpose is to provide a pressure-sensitive cover with a rotating member to facilitate the opening and closing operation of the lid.

Another object of the present invention is to provide a safety pin at a predetermined position inside the pressure lid to securely open and close the lid.

Another object of the present invention is to provide an opening and closing button on the upper side of the outer cover to minimize the use space during storage.
